VM527:1 Uncaught ReferenceError: countBirds is not defined

I get the "VM527:1 Uncaught ReferenceError: countBirds is not defined" message in the Chrome console when I enter: countBirds()

Any thoughts on this? Terry

That means there is no function called countBirds() defined

thank you. However, I am using a workspace from the video "The Problem with Globals" the function is defined as such: var count = 0;

function countBirds() { count += 1; return count + ' birds'; }

Terry, I was able to replicate the issue you describe. It didn't happen every time, but when it did, I simply refreshed the browser and it worked as expected. I'll raise an issue to look further in to this. In the meantime, I hope this helps!

Hi Terry Cone

I launched the workspace associated with the video and was able to get:

Maybe delete the workspace from the /workspaces dashboard and try again!

Regards,

Hi there. If I paste the code into the index.html page I can successfully call the function. Otherwise, the linked script gets me a uncaught error. It works for you, so possibly it is a setting I have in Chrome - at any rate, thank you for looking into this for me. I am a trial user and will not be continuing but thank you again. Terry
